Research ArticleOpen accessEvery word in the titleStability of Neodymium(III) Complexes of 4-Hydroxycoumarins with Anticoagulant ActivityIrena Kostova, Irina NikolovaComplexes of neodymium(III) with 4-hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one, 4-hydroxy-3-[1-(4-chlorophenyl)-3-oxobutyl]-2H-1-benzopyran-2-one and 4-hydroxy-3-[1-(4-nitrophenyl)-3-oxobutyl]-2H-1-benzopyran-2-one were synthesized by mixing of water solutions of neodymium(III) nitrate and the respective ligands, in amounts equal to metal: ligand molar ratio of 1: 3. The complexes were characterized and identified by elemental analysis, conductivity, IR and 1H NMR spectral data. DTA and TGA have been applied to confirm the compositions of … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 2 · 30 Jun 2006 · 7,554 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmunomodulatory and Antioxidant Effects of Stachys Japonica Miq. Ethanol Extract on Cyclophosphamide-Induced Immunosuppressed Mice and its Phytochemical CompositionXueping Jiang, Jianglong He, Yanjun Chen, Fang WangStachys japonica Miq. is an edible wild botanical drug and a traditional medicine in China. This study focused on examining the phytochemical profile and antioxidant properties of the ethanol extract of S. japonica Miq (SJEE) in vitro, as well as its immunomodulatory and antioxidant activities in cyclophosphamide (Cy)-induced immunosuppressed mice. The SJEE was analysed by UPLC-HRMS/MS. 36 Polyphenols, including flavonoids, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 13 Apr 2026 · 1,449 accessesView PDF Cite
